DETAILED DESCRIPTION

FIG. 1 depicts example components for automatic detection and control of multimedia applications, according to one aspect of the subject technology. A computing device (for example, tablet computer, notebook or personal computer, PDA, a smartphone, server, or television or other display device with one or more computing devices embedded therein or attached thereto) is configured with a multimedia subsystem 101 for operating system level management of multimedia data and other signals produced by hardware components of the computing device, various multimedia programs 102 executing on the computing device, or one or more operably connected multimedia component systems 103.

Multimedia programs 102 are application programs that operate independent of multimedia subsystem 101. Multimedia programs 102 may include one or more native applications (for example, installed on the computing device) and/or one or more web applications (for example, accessed over a network or embedded within a web-page displayed by a browser). For example, a multimedia program 102 may include a user-facing multimedia application such as a stand-alone media player, internet-radio application, a website providing audio or video content in a web browser, a browser component providing audio or video content, or other types of software for streaming or receiving streamed audio or video. In some implementations, a multimedia program 102 may include a software program for receiving audio data from a multimedia component system 103. For example, multimedia program 102 may be software installed on a computing device for communication with an audio/video (A/V) receiver.

Multimedia subsystem 101 includes an audio mixer 104 for volume and tone control of audio signals generated by multimedia programs 102 for output to audio hardware 105 of the computing device. Multimedia subsystem 101 includes a multimedia management component 106 (for example, a software library) for more detailed mixing and management of multimedia data before audio data is passed through audio mixer 104 or converted to audible audio signals. As will be described further, management component 106 detects active multimedia programs 102, verifies the detected programs accept remote control of their respective audio levels, and aggregates control over those programs through a user interface.

In various aspects, multimedia management component 106 may provide a registration interface 107 (for example, part of a application programming interface (API) framework) to receive registration information requests from multimedia programs 102 executing on the computing device. A multimedia program 102 may be configured (for example, by way of programming) to, when executed or instructed to playback multimedia content, operably connect to registration interface 107 (for example, via the API) and register itself with multimedia management component 106. Once multimedia program 102 is registered, multimedia subsystem 101 may receive streaming multimedia content (for example, audio and/or video data) from multimedia program 102.

In other aspects, a multimedia program 102 may provide an indication to registration interface 107 (for example, a notification sent via the API) that multimedia program 102 is active and accepts remote control of features provided by multimedia program 102 (for example, audio levels). Multimedia program 102 may then periodically provide multimedia subsystem (for example, via registration interface 107) content information for actively playing or queued multimedia content. Content information may include, for example, a title or description associated with the multimedia content. By querying interface 107 for this information, management component 106 may determine content information for a multimedia source (for example, an internet radio provider) associated with multimedia program 102. In some implementations, each multimedia program 102 may register itself at registration interface 107, and multimedia management component 106, on learning of a registered audio source from the registration, may query the audio source directly for content information.

As described previously, multimedia management component 106 may determine active sources of multimedia content by detecting registration of multimedia programs 102 at registration interface 107. In some examples, component 106 further determines that one or more active multimedia sources accept remote control of respective audio levels. Management component 106 may then send and receive messages to and from one or more multimedia programs 102 to control various aspects of multimedia programs 102, including increasing or decreasing volume of audio currently being streamed by corresponding multimedia sources, changing songs or stations, suspending/pausing, resuming or terminating playback, and the like. Management component 106 may send messages to a multimedia source 102 requesting, for example, various types of audio-related content information from the multimedia source (for example, title information, artist information, and the like).

In various aspects, management component 106 enumerates what multimedia programs 102 are providing audio and provides them to a multimedia service interface 108. Multimedia service interface 108 provides a service-level interface (for example, another part of the API framework) for providing user control over the enumerated multimedia programs 102. Accordingly, the subject technology provides a software control user interface (UI) 109, which may be graphically displayed to a user in the form of a dialogue box or similar graphic user interface for remote user-control over enumerated multimedia programs 102. In this respect, control UI 109 includes graphically displayed interactive volume controls for each of the enumerated multimedia programs 102, and is configured to remotely control the respective audio levels by graphic manipulation of respective interactive volume controls. As will be described further, control UI 109 may further display content information received from one or more enumerated audio programs.

Multimedia subsystem 101 may receive streaming multimedia content from a detected multimedia program 102, the audio program receiving the streaming multimedia content from a multimedia component system 103 located remote from the computing device. Management component 106 may receive from control UI 109 a query for multimedia programs 102 that accept remote control one or more multimedia features, return a list of programs, and then receive from control UI 109 one or more commands to control one or more features of multimedia component system 103. On receiving the one or more commands, management component 106 remotely controls, via the detected multimedia program 102, the one or more features of the multimedia component system 103 according to the received one or more commands.

FIGS. 2A and 2B depict diagrams of an example computing device, including a universal multimedia control displayed on a display screen for manipulation of multiple active multimedia sources, according to one aspect of the subject technology. A computing device 201 (for example, tablet computer, notebook or personal computer, PDA, a smartphone, GPS navigation device, or television or other display device with one or more computing devices embedded therein or attached thereto) is configured with program code for generating and displaying, on a touch-sensitive display screen 202, a virtual multimedia controller 203. According to the example of FIG. 2A, virtual multimedia controller 103 may be a stand-alone user interface that may be executed independently of other programs. Multimedia controller 203 may be graphically displayed as layered over at least a portion of other graphic user interfaces also displayed on display screen 202. In other examples, depicted by FIG. 2B, multimedia controller 203 may be embedded in, or part of, another program, such as a web browser 204.

According to the subject technology, multimedia controller 203 is provided for user-control of multimedia from multiple compatible software and hardware multimedia sources. Integration and communication between multimedia controller 203 and compatible multimedia sources is implemented as described with respect to FIG. 1. In some implementations, multimedia controller 203 is provided for display by software of multimedia management component 107. In this manner, multimedia controller 203 provides display of detected active multimedia sources, for example, running on computing device 201, or on other devices operably connected to the computer by wired or wireless network connection. On detecting active multimedia sources, the underlying code for multimedia controller 203 or management component 106 verifies that one or more of the multimedia sources accept remote control of respective multimedia levels.

Multimedia controller 203 includes graphically displayed interactive volume controls 205, one for each detected multimedia source. Each volume control 205 remotely controls an audio level for a verified source by graphic manipulation of the volume control. Volume controls 205 may be manipulated to control volume levels by a pointing device, such as a mouse, trackball or similar device. Where display screen 202 is a touch-sensitive display, volume controls 205 may be manipulated by contact with a portion of display screen 202 at a location corresponding to the volume control 205. Additionally, multimedia controller 203 may further determine, from one or more of the detected multimedia sources, respective content information for actively playing multimedia content. Content may include, for example, the name of a song or video being played. Once detected, the content information may be displayed in a content window 206 for a corresponding multimedia source, in connection with a respective volume control 205 for the multimedia source. Multimedia controller 203 is not limited to control of volume levels. Rather, multimedia controller 203 may include other controls, including, for example, a mute control for each multimedia source, tone controls, playlist controls (forward, backward, pause, next or previous song selection), or the like.

FIG. 3 is a flowchart illustrating an example process for detection and control of multimedia applications, according to one aspect of the subject technology. According to some aspects, the blocks of FIG. 3 may be executed by a computing device (for example, tablet computer, a desktop or notebook computer, PDA, smartphone, a television or other display device with one or more computing devices embedded therein or attached thereto, or the like). In this regard, the blocks of FIG. 3 may be performed within the context of operating a web browser provided by the computing device.

In block 301, a display of a graphic multimedia interface is initiated by a user. The multimedia interface provides a plurality of graphically displayed interactive controls for controlling multimedia features of a corresponding plurality of multimedia programs. A multimedia program may comprise a user-facing multimedia application, for example, a stand-alone media player, internet-radio application, a website providing audio content in a web browser, a website providing video content in the web browser, a browser component providing audio content, or a browser component providing video content. The interactive controls may include virtual dials, sliders, or buttons for controlling features such as a volume level, a playback of multimedia content, or a selectable list of available multimedia content.

On initiating the display of the graphic multimedia interface, in block 302, a plurality of multimedia programs available to receive streaming multimedia content from respective remote audio sources are detected by instructions associated with the multimedia interface. Detecting the multimedia programs may include, for example, receiving a plurality of registration requests from the plurality of multimedia programs at registration interface 106. In some aspects, a registration request is a request to add an active multimedia source to a list or group of registered active multimedia sources. On receiving the request, the multimedia source is registered with management component 106 (part of the multimedia subsystem 101). Accordingly, a plurality of active multimedia sources corresponding to the plurality of multimedia programs may be registered and subsequently identified in the list of registered multimedia sources.

In block 303, management component 106 determines that one or more of the plurality of multimedia programs accept remote control of one or more multimedia features. The determination may be made, for example, by virtue of being registered, or may be made by detecting one or more flags set at registration interface 107 for a multimedia program during the registration process. In block 304, the multimedia interface is displayed on a display screen associated with the computing device. The multimedia interface operates independent of the plurality of multimedia programs and includes one or more graphically displayed interactive controls for each determined multimedia program, each interactive control configured to remotely control a multimedia feature by graphic manipulation of the interactive control. In some implementations, the multimedia interface is a stand-alone graphic user interface similar to virtual multimedia controller 203 depicted in FIG. 2A. In other implementations, the multimedia interface is displayed as part of a web browser, similar to virtual multimedia controller 203 depicted in FIG. 2B.

In block 305, a user-initiated manipulation of an interactive control corresponding to a multimedia program is received, and, in block 306, a state of a multimedia feature for the corresponding multimedia program is changed according to the user-initiated manipulation of the interactive control. The state may be changed while keeping a current state of other multimedia features unchanged. In one example, manipulation of an interactive volume control triggers a command to adjust a volume level associated with a corresponding registered multimedia source. Accordingly, the volume level of audio for the registered multimedia source is adjusted while keeping volume level for other registered audio sources unchanged.

FIG. 4 is a diagram illustrating an example server system for detection and control of multimedia applications, including a processor and other internal components, according to one aspect of the subject technology. In some aspects, a computerized device 400 (for example, computing device 201) includes several internal components such as a processor 401, a system bus 402, read-only memory 403, system memory 404, network interface 405, I/O interface 406, and the like.
